Time to play! [12]: the answer

Here is the answer to our quiz Time to play! [12]

Thank you for your comments !

The pedunculated lesions (at least 2) were located in the antrum of the stomach.  The dog was rotated to the right, in order to move the existing fluid in the stomach toward the pyloro-duodenal junction.  As you can see during peristaltic activity, the nodules “float” and move back and forth…possibly mimicking an intussusception.  The lesions are moderately echogenic and partially layered, and seem bordered by a hyperechoic wavy mucosal line.  When asked after the ultrasound findings, the owner mentioned a recent episode of vomiting of undigested food.

Endoscopic biopsies were taken and the diagnosis was gastric inflammatory polyps with concurrent marked diffuse mucosal hyperplasia and moderate chronic neutrophilic and lymphohistiocytic gastritis (myriad of bacteria).

These lesions can be quite spectacular but not uncommon in miniature breeds.  In absence of clinical signs, follow-up ultrasound may be recommended.

  1. Sorry, but did these peduncle lesions result in a picture like intussepção in the stomach?
    What is the possible cause, please?

    • The lesions are originating from only one side of the gastric wall. Watching the pedunculated structures in real time, helps differentiating it from a circumferential intussusception. Gastric polyps are likely products of chronic gastritis and mucosal hyperplasia…I’m not sure why it is more commonly in small/miniature canine breeds. Another mystery to solve!
